Most Frequent Compressive Limb Neuropathies: A Literature Review

Abstract

Peripheral nerve injuries vary in length and severity, and they can occur secondary to trauma, compression and ischemia, leading to both motor and sensory neurological deficits. Nerve compression can occur in both the upper and lower limbs. These injuries can affect the quality of life, including the total or partial loss of the individual's productive capacity. The diagnostic methods are based on clinical criteria, but they may also include imaging and electroneurophysiological studies. A clinical examination using the Tinel and Phalen tests, for example, may suggest carpal tunnel syndrome. Complementary exams are used to confirm the diagnosis and rule out other possibilities, and the most used are electroneuromyography (ENMG), computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography (US). Depending on the type of injury, recovery may be spontaneous or may require conservative or surgical treatment.
